To of( whom t m d'1/ concern.'

lle it known that l, Ximian E. Tlf'nvr., a eitnien of the l'niteii States, residingV at vWilmington, in the eounty ot )Jew Hanover and State ot Xorth tarolina, have invented eertain new and useul improvements in Side .Bearings tor lailivay-tars, et' which the following is a speeilieation, referentey being had to the neeonipanying drawings, forming,- a port. hereof. v

invention relates to improvements in roheil side-bearings for railway ears.

niie-bearings in general of the Class herein dew-lived eonsist ot' numerous parts and are a eonstant'souree or" trouble and expense to niaintain in proper working condition. Home ot the more siinple designs use rollers which, when the roller has traveled to the end ot' its niovenient'and there is still further detlection of vthe truck with respect to the body of the ear, it becomes necessary tor the roller to slide causing tiat spots on the rolling surface which are very objectionable as the side-benring cannot work favorablyy under such Conditions.

loro the object, of my invention is to rozit ont durable eonstrnetion, that will yield freely with the movement between the ear body and the truck, and oit such shapevthat wear on its eontaet surfaees does not alter its shape and usefulness.

il/ith these and other objects hereinafter explained in view inyinvention consists in the construction' and eoinbination of elenients hereinafter deseribed and elaiined.

in the aeeoniganying drawings which .illustrate the preferred en'ibodiinent of niy invention: Figure l is a plan view of a side; bearino embodying iny invention applied as a trueli side-bearing, Flo'. 2 is a section ol saine showing the body sale-bearing in eontact with the roller in its central position, Fig. Ii is a part end view and part cross set:- t-ion of saine, Fig. e'- vis a sideview showing the roller in its extreme positions7 Fig. 5 shows a part section of a ear having a Sideeearinn"eznl'iodying niy invention applied to 'its truck bolster, Fig. shows a side bearing enibinlyino; my invention l'or application to a body holster ot a ear, partly in oross .seetion and partly au end view, lfig'. T .shows a partside view and part lonnitudinal seetion o1 saine.

Similar elmraeters designate similar parts throughout the several figures ot the drawe a side-bearing of simple, strong` Referring now to thex parts by number, l

is a. bearing' plate ot a side-hearing and is provided with sides i) and end stops or eross bars Il iorniing a housing in whieh is loeated a .spot-iai roller il. yhe roller el is provided with a lower rolling snrt'aee 5. an upper rolling surft'aee 6 and inclined sides T, the lower rolling surface beinfby ot greater radius than tlie upper rolling s ur'lfaee, thus causing theI roller to center itselt' by gravity. In order that the reliez' 4 inay always be in proper position on plate l, the plate is provided with,v teeth or projections 8 which are adapted to enter recesses kE) in the lower part ot the roller. The arrangement of teeth and recesses may be reversed by 'having the teeth onthe roller and the recesses in the plate without affecting their function and intent; of their purpose. l The portionot the ear body known as the body side-hearing; and wliieh isinterniittently in Contact with roller et is shown as l0, has a longitudinal movement with re- Speet to plate l.

In Fig. 4t the roller is shown in full lines in its extreme right handposition and in dotted lines as-Li in its extreme left hand position, l() and l0 representing the Corresliondinel positions ot the body side-bearing. The distanre between lines a--o and bfi). represent the :"ull movement of the body Sidebearingl diie ,to the rolling,` action ot the roller 4. lt will be noted that the roller has another important function which is, when it is at either of its extreme positions one ot iheilat suriares T is parallel with the'lower sortere of the bodyY sdefbearing, upon which the tial: surl'afje will slide in ease ot further movement. liront the foregoing deseription Ait will be seen that this sifle-bearingj can be designed `t'or average eonditions ot travel only and allowv the. sliding` feature totalie raro of the niaxinuun or unusual.movement,l therebv reflui-ingr the. .size and weightof partsto a xnininiuln and siniplifying' the eonstrurtion. y

ln is .shown a side-bearing ot this invention as it. actually appears applied to a trurk bolster of a railway flat ear in its normal position. lhe plato l is bolted to the top ol' a truck bolster ll and the loody sido-bearingl l() is bolted to the bodybolster l2 in surh a manner as to provide a small spaoe between the body side-bearing l0 and the roller -lA when the ear is standing normal.

in ities. t3 and T it will be noted that the housing formed by bottom plate l, sides 2L llt) and ends 3a is so constructed as toreceive and retain therein lthcroller 4a and is shown attached to a portion 13 of a body bolster.

The roller v-l-a is provided witha'removable pin 14 which projects through each side of the roller into the recesses l15 in the sides 2a oi. the housing, forming trunnions which retain the roller within the housing and the teeth 8a in operative communication With recesses D. The removable pin 14 is here shown expanded ateach end in order to keep l' claim is:

1. In aside-bearing the combination with a bearing plate provided with side 'walls,`of a roller engaging said bearing plate and providol'l with inclined fiat surfaces, means .for guiding the roller, comprising intereng' ug parts on the roller and the bearing l plate` and means for stopping the roller in position with a fiat. surface parallel with the bearing plate.

2. ln Iay side-hearing, the combination.with a bca ring plate, of av roller having an upper -milling,surface and a lower rollingsurface and iuf'flined fiat surfacestangent to oner ofi the rolling surfaces, and means for stop]'iing ille-'millerv in yposition with an inclined sur,- Yl'aveparallelwitli the bearing plate, couipi'isfr engaging pai-ls on l,the roller Vand bearing' plato. i' i' 'a I.. lnfa-sido-bearing, the 'combination withy a .liea'liiug plaefof a roller having'upper andv lower rolling snrt'accsand inclined flat :"n'i'acestangent to the rolling surface opposite said bearing plate, means for holding lli'e' roller inoperative position on the bearing plate, and'ineans for stopping the roller in 'position with an inclined sui-face parallel 'nith the bearing'plate, comprisingengag-y ing parisl on'tlie roller and bearing plate.
